The Moons of Jupiter
The charts below show the changing positions of Jupiter's four largest Moons, which are easily visible through a pair of modest binoculars or a small telescope as a series of pinpoints of light around Jupiter.
The east-west position of each moon relative to Jupiter is shown by a colored line. The planet's disk is represented by the gray strip that runs down the center of each column, which the moons past in front of when travelling from east to west (left to right), and behind when travelling from west to east (right to left).
The horizontal lines are drawn at midnight each day, in your local time – Fairfield time (EDT).
